Build resilient and scalable, cloud-native enterprise Java applications using the Quarkus framework.

Quarkus lets you live-reload your Java code, deliver continuous background testing, and automatically provide database instances--plus tons more productivity-boosting features! Quarkus in Action quickly gets you up to speed with Quarkus by building a real-world business application.

In Quarkus in Action, you will:

- Use Quarkus Dev mode to speed up and enhance Java development
- Understand how to use the Dev UI to observe and troubleshoot running applications
- Automatic background testing using the Continuous Testing feature
- New frameworks and libraries such as Quarkus Messaging, gRPC, and GraphQL
- Simplify deployment of applications into Kubernetes and OpenShift
- Automatic management of remote services such as databases and message brokers via Docker containers
- Set up observability for applications by using metrics, health checks and distributed tracing

Quarkus in Action is written by Martin Stefanko and Jan Martiska, Red Hat engineers who are both active contributors to the Quarkus project. In it, you’ll learn how Quarkus works and how you can integrate it into your stack for more productive Java development. Discover what makes Quarkus different from classic enterprise Java frameworks, how Quarkus streamlines creating cloud-native applications, and makes deployment easy.

Foreword by Markus Eisele.

About the technology

Choose a Java framework that’s as modern as your applications! Quarkus is a cloud-first framework designed for speed and cost optimization. It’s Kubernetes-aware by default and includes amazing productivity features like live reloading, continuous testing, and a developer-friendly UI that lets you code fluidly without tedious setup.

About the book

Quarkus in Action provides a carefully designed learning path through Quarkus’ key features and use cases. You’ll learn hands-on by implementing a working car rental application with a cloud-native microservices design that includes Kubernetes, SQL and NoSQL databases, messaging, and observability. Along the way, you’ll learn how Quarkus simplifies deployment on cloud platforms like OpenShift.

What’s inside

Martin Stefanko has been working on Red Hat’s middleware portfolio for the last seven years. He is responsible for the SmallRye Health and Narayana LRA extensions and is also contributing to several other core extensions mostly around MicroProfile integration. He is also involved in several MicroProfile specifications.

Jan Martiska has been a Red Hatter for over 10 years and spent most of this tenure working on open-source, Java-based application platforms. Jan furthered Quarkus’ observability capabilities by leading the MicroProfile Metrics specification and taking care of the relevant Quarkus extension. He’s also contributed a lot into the SmallRye GraphQL extensions, both server and client.
